Description

PCT/AU2010/001493 Received 16/02/2012 Improved Boat Storage Rack Field of the Invention 5 This invention relates to a configurable storage rack for securely supporting a multiplicity of rowing boats during storage, and more particularly to a storage rack which is capable of being collapsed when the storage rack is in its normally upright position. Background to the Invention 10 At present, handling and storage of rowing boats and related equipment such as oars is typically managed by the users manually lifting and moving these boats and equipment to and from rowing sheds to transporting equipment such as trolleys and or direct to water. Conventional rowing boat storage racks are typically made of fixed horizontal and vertical struts up to a height 15 generally set by how far a rowing boat user/s can safely lift to when storing and removing their rowing boat, which often restricts the number of rowing boats that can be stored within a storage area. Further, these conventional storage racks are typically fixed dimensionally for the one type of rowing boat, limiting the ability to store varying size and weight rowing boats. The increase of occupational safety regulation and requirements has also limited the amount of weight a person 20 can carry and how high they can lift it. These conventional rowing boat storage racks are generally made of strong materials such as steel, are therefore heavy and awkward to move easily, hence they require dedicated landscape or floor space to sit, which often restricts the number and type of boat storage racks that can be 25 used within a defined storage area, hence again restricting the number of rowing boats that can be stored safely and effectively. Further, rowing boat storage areas such as boat sheds tend to exist close to water foreshores where the price of land and space areas is relatively high and often scarce, exacerbating the cost effectiveness of conventional rowing boat storage rack systems. 30 It is an object of this present invention to overcome or substantially ameliorate the disadvantages of the prior art by providing a rowing boat storage rack system which reduces the incidence and AMENDED SHEET PCT/AU2010/001493 Received 16/02/2012 2 amount of physical injury due to lifting heavy rowing boats, thereby permitting users to more easily and safely move rowing boats to and from storage. It is another object of this present invention to provide a rowing boat storage rack system which reduces the floor area required to stand a boat storage rack system, thereby permitting users to 5 increase the number of boat storage racks within a defined storage floor space area, which correspondingly increases the number of rowing boats that can be stored. Summary of Invention 10 The present invention provides a boat storage rack system comprising at least one "L" shaped frame, a head beam, a winch assembly, a winch control, at least one rack arm, at least one roller assembly, a roller linkage assembly and a safety guard. The arrangement is such that the "L" shaped frame is preferably a right angle frame with a 15 vertical straight back and horizontal flat based bottom made of a metal material or any other suitable material, which is strong, durable and meets the requirements of the invention. On the front face and near the bottom of the "L" shaped frames is a plurality of fixed struts aligned horizontally between each "L" shaped frame. Fixed on top and aligned horizontally between the top of the "L" shaped frames is fixed two struts which preferably have a winch assembly 20 removably attached in the centre with braces angled down towards the inside and bottom of the "L" shaped frames for stability. It is preferred that the winch assembly has a swivel hook that removably connects to the centre of the head beam. Preferably the head beam aligns horizontally between the "L" shaped frames 25 and is fixed at either end to a roller assembly. Connected to the winch assembly is the winch control that has at least one switch or button which is adapted to activate and de-activate one or more features of the winch assembly. It is preferred that the top side of the horizontal flat based bottom is preferably adapted with 30 fixed rollers that removably engage with an inverted "U" channel to form a sliding bar to enable the user to easily retrieve and or store a rowing boat from the lowest point of the "L" shaped frames.
